Thermal basics
What is Thermal Pollution?
Thermal pollution occurs when there is a harmful change in the temperature of natural water bodies, typically due to human activities. This change can involve either heating or cooling of the water environment.
Key Characteristics
- Temperature Change: Sudden or gradual increase/decrease in water temperature
- Origin: Primarily from industrial processes and power plants
- Impact Range: Affects both local and downstream ecosystems
- Duration: Can be temporary or long-lasting
Natural vs. Artificial Temperature Changes
Natural Temperature Variations
- Seasonal changes
- Day/night cycles
- Geographic location
- Water depth variations
Artificial Temperature Changes
- Industrial cooling processes
- Power plant operations
- Urban runoff
- Deforestation affecting water temperature
Measurement and Detection
- Temperature monitoring systems
- Thermal imaging
- Biological indicators
- Water quality assessments
